    Asked by committee_forms on April 18, 2017 at 02:13 AM

    I have a gate access form where people enter their toll way card number. Tollway card has 8 digits eg. 12345678 but I only need last five. Is there a way where read only field recognize last 5 digits (45678) and fill it automatically? Thanks

    I am not quite sure if I understand how your form works. Can you provide us more details like steps on how your users use your form? Do they manually fill out the form? If so, then you can just add instructions telling your users that they should enter the last 5 digit of their card number. 

    However, I do see that your form titled "test" is already using the Substring widget, which allows you to get part of an input field.

    We'll wait for your response.
